Pro-Line Individual 2 1/4x2 1/4" Slide Protector Sleeves for 6x6 Mounted Transparencies, Box of 100

• PRO-LINE Slide Sleeves are designed to protect standard 35mm slides and 120 size medium format, mounted transparencies. Slide sleeves are clear on two sides, or clear front with a frosted back for enhanced viewing of 35mm slides.
• Because PRO-LINE's specially formulated polypropylene has a physical density that is less than other sleeving materials, it is more pliable and gentle to your film. Strong and durable, PRO-LINE won't become brittle or abrade film. PRO-LINE sleeving is optically clear, color neutral, and has a unique anti-Newton ring surface that reduces distracting Newton rings as well as minimizing the actual surface area that is in contact with your film.
